Most of the cars were Buicks; two Chevy Camaros joined the group, and one Chevy pickup.

The pickup owners are in the Buick Club, too. Jim Drury of Birch Run and his wife Ruth made the trip in the 1972 Cheyenne pickup.

Drury said when he was called about the movie, the caller was interested in his son's boattail Riviera, which is not available.

The Drurys also have a 1955 Century and a 1959 LeSabre, but he said when he mentioned the truck, that's what they wanted.

"I told them it wasn't restored," he said. "They didn't care."

One of the Camaro owners is Aileen England of Burton, who drove her 19701/2 Z28.

She said the filming continued through the night at the Detroit Fairgrounds, until about 3:30 a.m.

Some of the extras took their own costumes, others including England were fitted by the movie-makers.

"I had a one-piece jumpsuit - it was light peach, with flowers on it," she said. "I had a big jade medallion and a green scarf.

"When I came out of the costume area, everybody was laughing at me."

England said the extras spent a lot of time Tuesday night just hanging out, talking, waiting for something to happen. They were filmed inside the coliseum, leaving the building and outside in the parking lot, as if they were leaving a game.

David Bothamly of Grand Blanc drove one of his 1968 Wildcats on the trip. There was a problem with the windshield wiper of the driver's side, so before leaving Grand Blanc they swapped the passenger side wiper over; he bought some Rain-X and was good to go.

Bothamly has one of each body type of 1968 Wildcat: Two-door and four-door hardtops, four-door sedan and convertible.

"Buicks are like salt-and-pepper sets," he said. "You've got to collect all of them."

Another Wildcat was a convertible owned by Ray and Genevieve Dutrizac of Burton.

"It's the first time out of the barn for this one in two years," he said.

The group picked Bill Salisbury of Swartz Creek to lead, driving his 1968 GS 400.

"I've got two maps," he said.

Brian Kitchen of Flint Township, current director of the local chapter of the Buick Club, drove his 1973 Riviera.

"I bought it from the original owner in 1986, for $600," he said. "Her husband told her she had to sell it because it was too big, too old, too bad on gas."

He said it's a great car for road trips.

"I love that car," he said. "It's just like one of my kids."

Among the others making the trip were Charlie Jones of Byron, who drove his 1965 Buick Special convertible; Duane and Eunice Williams of Flint with a boattail Riviera; Bryan and Valerie Page of Burton, with a 1969 Camaro; and Gary Minch of Davison, with a 1966 Gran Sport.
